Water purification device and water purification system

Abstract

The invention discloses a water purification device and a water purification system. The water purification device comprises: a water purification body provided with a purified water outlet; and a valve mechanism comprising a valve body, a valve core and a spring, wherein a valve cavity is formed in the valve body, a valve water inlet and a valve water outlet which are both communicated with the valve cavity are formed in the valve body, the valve body is connected to the purified water outlet so as to form butt joint between the valve water inlet and the purified water outlet, the valve water outlet is communicated with a water purification faucet, the valve core and the spring are both arranged in the valve cavity, and the spring abuts against the valve core, so that the valve core can block the valve water inlet with certain pre-tightening force. Under the conditions that the pressure of a concentrated water side is reduced and a water purification keel is closed, drinking water left between a water purification faucet and a purified water outlet cannot enter a water purification body by additionally arranging a valve mechanism, so that the part of drinking water can keep the original quality and always meets the drinking standard.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification device and a water purification system. Background technique [0002] The water purification device (or filter membrane component) used to obtain drinking water is usually provided with a filter membrane. On the one hand, tap water enters the water purification device through the tap water inlet of the water purification device, and the tap water entering the water purification device passes through the filter. Drinking water (or purified water) is formed behind the diaphragm, and the water remaining on the outside of the filter diaphragm forms concentrated water, and the drinking water flows out through the water purification outlet on the water purification device. It may be advisable to call the side with concentrated water in the water purification device the concentrated water side, and the side with drinking water as the clean water side. Ho...

AI Technical Summary

Problems solved by technology

[0004] When the pressure of tap water decreases, the pressure difference between the concentrated water side and the purified water side decreases (the concentrated water side and the purified water side need to maintain a certain pressure difference to obtain standard drinking water), or the purified water faucet is closed so that When the drinking water between the clean water faucet and the clean water outlet no longer flows out, the water between the clean water faucet and the clean water outlet will permeate toward the concentrated water side, so that the distance between the clean water faucet and the clean water outlet The concentration of drinking water increases, which leads to the fact that this part of drinking water does not meet drinking standards
